Texas Instruments TCM29C18
The TCM29C18, TCM29C19, TCM129C18, and TCM129C19 are low-cost single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM line filters. These devices incorporate both the A/D and D/A functions, an antialiasing filter (A/D), and a smoothing filter (D/A). They are ideal for use with the TMS320 DSP family members, particularly those featuring a serial port such as the TMS32020, TMS32011, and TMS320C25.| Part No. | TCM29C18 |

FEATURES
TABLE Number of Pins: 16 Coding Law: µ-Law Variable Mode: 64 kHz to 2.048 MHz Fixed Mode: 2.048 MHz (TCM29C18, TCM129C18), 1.536 MHz (TCM29C19, TCM129C19) 8-Bit Resolution 12-Bit Dynamic Range Primary applications include:● Digital encryption systems
● Digital voice-band data storage systems
● Digital signal processing These devices are designed to perform encoding of analog input signals (A/D conversion) and decoding of digital PCM signals (D/A conversion). They are useful for implementation in the analog interface of a digital signal processing system. Both devices also provide band-pass filtering of the analog signals prior to encoding, and smoothing after decoding. The TCM29C18 and TCM29C19 are characterized for operation over the temperature range of 0°C to 70°C. The TCM129C18 and TCM129C19 are characterized for operation over the temperature range of – 40°C to 85°C. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
